A power storage system includes an AC/DC converter, a first control device, a power storage device, and a load. The first control device includes a measuring portion that measures the amount of power consumed by the load, a predicting portion that predicts the demand for power consumed by the load on the basis of the amount of power consumed by the load, and a planning portion that makes a charge and discharge plan of the power storage device on the basis of the demand for power predicted by the predicting portion. The power storage device includes a second control device, a DC/DC converter, a first battery cell group, and a second battery cell group. The power storage device is placed in an underfloor space surrounded by a base and a floor of a building.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A power storage system comprising: a control device; and a power storage device configured to supply power to a load, wherein the control device includes: a measuring portion configured to measure an amount of power consumed by the load, a predicting portion configured to predict the demand for power consumed by the load on the basis of the amount of power consumed by the load, and a planning portion configured to make a charge and discharge plan of the power storage device on the basis of the demand for power predicted by the predicting portion.
2. The power storage system according to claim 1 , wherein the load is a television, a personal computer, a microwave, a refrigerator, or an air conditioner.
3. The power storage system according to claim 1 , wherein the predicting portion is configured to predict the demand for power consumed by the load during a day on the basis of the amount of power consumed by the load during the previous day.
4. The power storage system according to claim 1 , further comprising an indicator configured to show the amount of power consumed by the load.
5. The power storage system according to claim 1 , further comprising a router through which the amount of power consumed by the load is configured to be shown on a smartphone or a tablet.
6. The power storage system according to claim 1 , further comprising a power storage controller configured to control the power storage device to be discharged in day time and be charged in night time.
7. A power storage system comprising: an AC/DC converter; a control device; and a power storage device configured to supply power to a load, wherein the control device includes: a measuring portion configured to measure an amount of power consumed by the load, a predicting portion configured to predict the demand for power consumed by the load on the basis of the amount of power consumed by the load, and a planning portion configured to make a charge and discharge plan of the power storage device on the basis of the demand for power predicted by the predicting portion, wherein the power storage device comprises: a DC/DC converter, a first battery cell group, and a second battery cell group, wherein one terminal of the DC/DC converter is electrically connected to one terminal of the AC/DC converter and one terminal of the first battery cell group, and wherein the other terminal of the DC/DC converter is electrically connected to the one terminal of the AC/DC converter and one terminal of the second battery cell group.
8. The power storage system according to claim 7 , wherein the first battery cell group and the second battery cell group each include a plurality of battery cells connected in series in which each battery cell includes a first electrode, a second electrode, and an electrolytic solution between the first electrode and the second electrode.
9. The power storage system according to claim 7 , further comprising: a first switch between the one terminal of the AC/DC converter and the one terminal of the first battery cell group; and a second switch between the one terminal of the AC/DC converter and the one terminal of the second battery cell group.
10. The power storage system according to claim 7 , further comprising: a first current detector electrically connected to the other terminal of the first battery cell group; and a second current detector electrically connected to the other terminal of the second battery cell group.
11. The power storage system according to claim 7 , wherein the load is a television, a personal computer, a microwave, a refrigerator, or an air conditioner.
12. The power storage system according to claim 7 , wherein the predicting portion is configured to predict the demand for power consumed by the load during a day on the basis of the amount of power consumed by the load during the previous day.
13. The power storage system according to claim 7 , further comprising an indicator configured to show the amount of power consumed by the load.
14. The power storage system according to claim 7 , further comprising a router through which the amount of power consumed by the load is configured to be shown on a smartphone or a tablet.
15. The power storage system according to claim 7 , further comprising a power storage controller configured to control the power storage device to be discharged in day time and be charged in night time.
